Remark 4.5 The estimates (REF )–(REF ) are established in [1]} up to unspecified constants depending on \(p\) . This is a consequence of the results of [2]}. More generally, the results of [2]} allows us to get Cwikel-type estimates for any interpolation space between \({L}_2\)  and \({K}\)  (see [1]}).
